We're trying to create our own Javascript library to replace jQuery and reduce overhead. We're wanting to call functions from the global scope using the this keyword, but the script is breaking in our foreach loop. How do we callback an object inside or custom "each" function using our $(this).getAtt('data-src') function rather than a.getAttribute('data-src')
this is defaulting to the window's object. Here's a minimized version of our library
var $=(function(){
'use strict';
var c = function(w){
if(!w)return;
if(w==='document'){this.elems=[document];}
else if(w==='window'){this.elems=[window];}
else {this.elems=document.querySelectorAll(w);}
};
c.prototype.each = function(callback){
if(!callback || typeof callback !== 'function')return;
for(var i = 0, length = this.elems.length; i < length; i++){callback(this.elems[i], i);}return this;
};
c.prototype.setAtt=function(n,v){this.each(function(item){item.setAttribute(n,v);});return this;};
c.prototype.getAtt=function(n){return this.elems[0].getAttribute(n);};
var init=function(w){return new c(w);};return init;
})();
function loadImgs(){
$("img[data-src]").each(function(a,b){
console.log(a.getAttribute('data-src'));
console.log($(this).getAtt('data-src'));
});
}
And our minimized HTML :
<a onclick="loadImgs();">lazyload</a><br>
<img src="spacer.gif" alt=""/></div><img class="lazyLoad" data-src="replacer.jpg" alt="">
Pass the calling context you want (the element) to the getAttribute method by using .call().
You also need the c constructor to set the elems property to the argument if the argument is an element:
} else if (w instanceof HTMLElement) {
this.elems = [w];
}
for (var i = 0, length = this.elems.length; i < length; i++) {
callback.call(this.elems[i], this.elems[i], i);
// ^^ "this" in callback
// ^^ first argument to callback
// ^^ second argument to callback
}
var $ = (function() {
'use strict';
var c = function(w) {
if (!w) return;
if (w === 'document') {
this.elems = [document];
} else if (w === 'window') {
this.elems = [window];
} else if (w instanceof HTMLElement) {
this.elems = [w];
} else {
this.elems = document.querySelectorAll(w);
}
};
c.prototype.each = function(callback) {
if (!callback || typeof callback !== 'function') return;
for (var i = 0, length = this.elems.length; i < length; i++) {
callback.call(this.elems[i], this.elems[i], i);
}
return this;
};
c.prototype.setAtt = function(n, v) {
this.each(function(item) {
item.setAttribute(n, v);
});
return this;
};
c.prototype.getAtt = function(n) {
return this.elems[0].getAttribute(n);
};
var init = function(w) {
return new c(w);
};
return init;
})();
function loadImgs() {
$("img[data-src]").each(function(a, b) {
console.log(a.getAttribute('data-src'));
console.log($(this).getAtt('data-src'));
});
}
<a onclick="loadImgs();">lazyload</a><br>
<img src="spacer.gif" alt="" /></div><img class="lazyLoad" data-src="replacer.jpg" alt="">
I am trying to create a callback functionality or at least that is how I name it. The main purpose is to call function from an array with the same context and to be able to call the next function in the array from the currently executing function.
This is the code that I have came up with:
function callCallbackChain(context, callbackChain, params) {
callbackChain.push(function () {
return true;
});
for (var i = 0, len = callbackChain.length - 1; i < len; i++) {
var cb = callbackChain[i];
var next = callbackChain[i + 1];
if (typeof cb === "function") {
cb.apply(context, [next].concat(params));
}
}
}
var callbackChain = [
function (next, foo) {
console.log('1 function call', arguments);
this.innerHTML = this.innerHTML + "function called + context:" + foo + "<br>";
next()
},
function (next, foo) {
console.log('2 function call', arguments);
this.innerHTML = this.innerHTML + "function called + context:" + foo + "<br>";
next()
},
function (next, foo) {
console.log('3 function call', arguments);
this.innerHTML = this.innerHTML + "function called + context:" + foo + "<br>";
next()
}
];
var d = document.querySelector("#conent");
callCallbackChain(d, callbackChain, ["param from the main function"]);
<div id="conent">
Initial Content
</div>
I can't seem to be able to set next function properly. It is something like a middleware.
Your next function must not actually be the next function in the chain.
Its the intent to run the next function.
function run(context, chain, params) {
var inner_run = (context, chain, params, index) => {
next = () => inner_run(context, chain, params, index + 1);
if (index < chain.length) chain[index].apply(context, [next].concat(params));
};
inner_run(context, chain, params, 0);
}
var chain = [
function (next, foo) {
this.first = true
console.log('first', arguments);
next()
},
function (next, foo) {
this.second = true
console.log('second', arguments);
// not calling next()
},
function (next, foo) {
this.third = true
console.log('third', arguments);
next()
}
];
var context = {};
run(context, chain, ["param"]);
console.log('context', context);
You need to bind it on the fly:
var nextelem=0;
function next(params...){
temp=nextelem;
nextelem++;
callbackChain[temp].bind(context)(next,...params);
}
//pass it
nextelem=1;
callbackChain[0].bind(context)(next);
My problem is that I'm having a Function A which calls at one point another function, let's call it Function B (getChildContent) and needs the return value of Function B in order to proceed. I know that it's because of Javascripts Asynchronous Nature, and i tried to solve it with a callback. But i can't get it work properly.
FunctionA(){
//some Code.....
else {
for(i in clustertitles) {
if(S(text).contains(clustertitles[i])) {
var parent = {};
parent.ClusterName = clustertitles[i];
parent.Functions = [];
var str = '== ' + clustertitles[i] + ' ==\n* ';
str = S(text).between(str,'.').s;
var caps = parseFunctions(str);
for(y in caps) {
//var content = getChildContent(caps[y]);
getChildContent(caps[y], function(content) { //Function call
var child = {};
child.FunctionName = caps[y];
child.Content = [];
child.Content.push(content);
parent.Functions.push(child);
console.log(content);
});
}}}
}
function getChildContent (capname, callback) {
t = capname.replace(' ', '_');
bot.page(t).complete(function (title, text, date) {
var str = S(text).between('== Kurzbeschreibung ==\n* ', '.').s;
if(str === undefined || str === null || str === '') {
throw new Error('Undefined, Null or Empty!');
}
else {
var content = {};
str = parseTitles(str);
content.Owner = str[0];
content.Aim = str[1];
content.What = str[2];
content.Who = str[3];
content.Steps = str[4];
content.Page = 'some URL';
callback(content);
}
});
}
So in Function A I'm trying to call getChildContent from a for-Loop and pass the current string from caps-array. For each String in caps-array getChildContent() makes a http request over a node.js module and retrieves a string. With this string i'm building an object (content) which is needed in Function A to continue. However the 'console.log(content)' in Function A just prints out the object which is created with the last string in caps-array, but for many times. E.G. if caps-array has 5 entries, i get 5 times the object which is created with the last entry of caps-array.
How can i manage the loop/callback to get every time the right object on my console?
Your loop should call another function that preserves the value of y, something like this:
FunctionA(){
//some Code.....
else {
for(i in clustertitles) {
if(S(text).contains(clustertitles[i])) {
var parent = {};
parent.ClusterName = clustertitles[i];
parent.Functions = [];
var str = '== ' + clustertitles[i] + ' ==\n* ';
str = S(text).between(str,'.').s;
var caps = parseFunctions(str);
for(y in caps) {
yourNewFunction (y, caps, parent);
}}}
}
function yourNewFunction (y, caps, parent) {
getChildContent(caps[y], function(content) { //Function call
var child = {};
child.FunctionName = caps[y];
child.Content = [];
child.Content.push(content);
parent.Functions.push(child);
console.log(content);
});
}
function getChildContent (capname, callback) {
t = capname.replace(' ', '_');
bot.page(t).complete(function (title, text, date) {
var str = S(text).between('== Kurzbeschreibung ==\n* ', '.').s;
if(str === undefined || str === null || str === '') {
throw new Error('Undefined, Null or Empty!');
}
else {
var content = {};
str = parseTitles(str);
content.Owner = str[0];
content.Aim = str[1];
content.What = str[2];
content.Who = str[3];
content.Steps = str[4];
content.Page = 'some URL';
callback(content);
}
});
}
There are 2 ways to do so.
Put the loop inside a function, execute your callback after the loop is done. (Problematic if you are doing async call inside the loop.
function doLoopdiloopStuff() {
for() {
}
callback();
}
The other way, the way i prefer looks like this:
for(var i = 0; i < stuff || function(){ /* here's the callback */ }(), false; i++) {
/* do your loop-di-loop */
}
In another example:
for (var index = 0; index < caps.length || function(){ callbackFunction(); /* This is the callback you are calling */ return false;}(); index++) {
var element = caps[index];
// here comes the code of what you want to do with a single element
}
Im wondering in the following code, how could I set the callback property "value" to null?
The code takes a bunch of ids (31, 32 ,33) and then uses a callback function to monitor changes to values of these ids. When I run the code again using the same IDs, is there a way to set the callback property to null?
obsids = new Array();
function list() {
if (arguments.length) {
leng = arguments.length;
for (i = 0; i < leng; i++) {
obsids[i] = new LiveAPI(callback, "id "+arguments[i]);
obsids[i].property = "value";
}
}
function callback(args) {
outlet(0, args[0] + " " + args[1] + " " + this.id);
}
}
You will need a specific callback for each obsids[i], and you need to create them in a closure for not loosing i.
function list() {
var obsids = [];
for (var i=0, len = arguments.length; i < len; i++)
obsids[i] = createApi("id "+arguments[i]);
function createApi(id) {
var obsid = new LiveAPI(function callback(args) {
obsid.property = null;
outlet(0, args[0] + " " + args[1] + " " + this.id);
}, id);
obsid.property = "value";
return obsid;
}
return obsids;
}
EDIT
The lesson, learned with the help of #Alex, is that you should never put function declarations in block scope. Not that I intended to do this, but if you slip up, it can cause big problems.
I have a script file that seems to be getting compressed via Google Closure incorrectly. When I run my app with the original code, all works fine. But when I try to compress it with Google Closure, some errors get introduced.
I am NOT using the advanced option; I'm using the basic, default mode
Obviously I can't expect anyone to debug the compressed file, but I'm hoping someone can look at the uncompressed code and let me know if I'm somehow doing something insanely stupid that would trick Closure.
Some notes on the minified code:
Closure is inlining BEFramework.prototype.hstreamLoad and BEFramework.prototype.hstreamEvalJson, and seems to be utterly removing the helper functions getDeleteValue, getValueToDisplay, getDisplayForLabel and likely others.
Uncompressed file is below.
This code can manually be compiled by closure here, which should reproduce the symptoms described above.

When you use closure compiler you're giving up some control over your code. It will do all sorts of tricks, and potentially remove unused code.
It appears as though your functions are not removed, but are renamed.
For example, your call to getDeleteValue...
getDeleteValue(subprop, currentValue)
is now...
l(g,r)
Because getDeleteValue was not exported, Closure renamed it.
Working with Closure Compiler takes a bit of finesse and quite a bit of documentation scouring until you're familiar with how it works.
Well, there are too many errors to think of. First of all, I don't understand if you want static reference or instantiated values. You are not using jsDoc tags or anything like that. The Compiler does it's best work only with the corresponding jsDoc tag. You're logic is very weird and ill formulated. Prototype alternations, etc, all happening in an IIFE(immediately invoked function expression). Are your functions static? Are they constructors? Are we human or are we dancer?
an IIFE executes before the DOMContentLoaded event is fired by the browser. The most you can do is a jQuery IIFE equivalent $(function() {})(); which binds that to the DOMReady or DOMContentLoaded callback. You are defining inline functions inside blocks, which is not even in the ECMA Language.
While most script engines support Function Declarations within blocks it is not part of ECMAScript (see ECMA-262, clause 13 and 14). Worse implementations are inconsistent with each other and with future EcmaScript proposals. ECMAScript only allows for Function Declarations in the root statement list of a script or function. Instead use a variable initialized with a Function Expression to define a function within a block.
var myFunctionName = function (params) {};
You are also missing loads of semi-colons. Automatic semi-colon insertion on interpretation of your JS is not exactly flawless, so make a habit out of it.
Relying on implicit insertion can cause subtle, hard to debug problems. Don't do it. You're better than that.
There are a couple places where missing semicolons are particularly dangerous:
// 1.
MyClass.prototype.myMethod = function() {
return 42;
} // No semicolon here.
(function() {
// Some initialization code wrapped in a function to create a scope for locals.
})();
var x = {
'i': 1,
'j': 2
} // No semicolon here.
// 2. Trying to do one thing on Internet Explorer and another on Firefox.
// I know you'd never write code like this, but throw me a bone.
[normalVersion, ffVersion][isFF]();
var THINGS_TO_EAT = [apples, oysters, sprayOnCheese] // No semicolon here.
// 3. conditional execution a la bash
-1 == resultOfOperation() || die();
So what happens?
JavaScript error - first the function returning 42 is called with the second function as a parameter, then the number 42 is "called" resulting in an error.
You will most likely get a 'no such property in undefined' error at runtime as it tries to call x[ffVersion][isIE]().
die is called unless resultOfOperation() is NaN and THINGS_TO_EAT gets assigned the result of die().
Why?
JavaScript requires statements to end with a semicolon, except when it thinks it can safely infer their existence. In each of these examples, a function declaration or object or array literal is used inside a statement. The closing brackets are not enough to signal the end of the statement. Javascript never ends a statement if the next token is an infix or bracket operator.
This has really surprised people, so make sure your assignments end with semicolons.
